WILLIAM W. FARNSWORTI'I, OF LITTLEION, COLORADO.

RENOVATOR.

Application filed January 21, 1918.

To all whom, it may concern Be it known that 1, 1V ILLIAM W. FARNS- WORTH, a citizen of the United States, residing at Littleton, in the county of Arapahoe and State of Colorado, have invented certain new and useful Improvements in Renovators, of which the following is a specification.

This invention relates in general toimprovements in renovators, but more specifically to improved means whereby the dust or oreign matter may be dislodged or agitated by means of a blast of air and which blast serves the further function of conveying away the agitated dirt or foreign matter.

A further object is to provide an improved device of this character in which the dust or foreign'matter is disturbed by a blast of air and which device is provided with means Wherebythe dust laden air Will be clarified and the clarified air used over and over A further object is to provide an improved device of this character which will be of a simple, durable and compact structure and effective and eiiicient operation.

To the attainment of these ends and the accomplishment of other new and useful ob- )GCtS as will appear, the invention consists the features of novelty in substantially the construction, combination and arrangement of the several parts, hereinafter more fully described and claimed and. shown in the accompanying drawing, illustrating this invention and in which;

Figure 1 is a view partly in side elevation and partly in vertical longitudinal section, of an improved device of this character, constructed in accordance with the principles of this invention.

Fig. 2 is a top plan view of Fig. 1 with parts in section and with parts broken away.

Referring more particularly to the drawings, the numeral 10 designates generally a cleaning head having an inlet opening 11, adapted to be moved over the surface to be cleaned. The head may be of any desired size and configuration and is provided with a discharge outlet opening 12.

A blast creating device 13, preferably in the form of a fan is arranged within a chamber 14 and this chamber has communi cation with the head through the opening 15. p

The blast creating device 13 is operated in any desired or suita le manner, preferably Specification of Letters Patent.

Patented Oct. 15, 1918.

Serial No. 212,859.

by means of a motor 16, and which motor receives its energy from any suitable source, and is preferably of the electric type. Arranged within the head 10 and preferably ad acent the opening 11 is a casing or chamber 17 of any desired size and configuration, but is preferably of a length to extend substantially across the opening 11. This chamber is supported in any desired or suitable manner and is provided with one or more series of openings 18 preferably in the bottom thereof, which form communication between the interior of the chamber 17 and the head 10, and these openings 18 are preferably arranged at an angle with respect to the surface over which the opening 11 than the sack 21.

sack 22 is connected with the discharge let opening 12 of the cleaning head, and end of this sack 22 may be detachably secured inposition in any suitable manner, such as by means of fastening devices 23, while the portions of the sack 21 maybe I'BIIIOVC ly securedto the tubes or pipes 19 in any suitable manner, such as by means of the fastening devices 24.

he casing 17 is preferably removably secured within the cleaning head, although it is of course to be understood that if desired, the casing may be formed therein during the course of manufacture. When the casing is removably held in position, any suitable means may be provided for thus holding it, such as the securing devices 25, which are adjustably mounted on a portion of the cleaning head and have engagement with the ends of the casing.

The casing 17 is also removably connected with the pipes 19 so that when it is desired to remove the casing, all that is necessary is to adjust the fastening devices and detach the casing from the pipes 19, when the casing may be readily removed.

In operation, the blast creating device 13 outlet opening 12 and into the sack or casing 23. "This sack being of a porous material, the air Wlll pass through the wall thereof into the sack or casing 21, and during such passage of the air, it will be clarified by the removal of the dirt and foreign matter therefrom. The air blast having been discharged 1nto the sack 21 will pass through the outlet portions 20 thereof into the pipes 19 and will be conveyed through these pipes into the casing 17 to be discharged therefrom through the openings 18 at an angle to and against the movedfrom the cleaning head and then discharged through the outlet opening 12 into the purifying or clarifying device. Thus it will be manifest that the same air can be used over and over again.

While there is shown two series of openings 18 in the bottom of the casing 17 it is of course, to be understood that both of these series of openings may not be necessary, and it is also to be understood that any desired number of openings may be provided.

What is claimed as new 15: 1. A renovator embodying a clean ng head,

a casing disposed within the cleaning head and having discharge outlets disposed to direct a blast of air against the surface to be cleaned, a suction creating device within the cleaning head, a. motor supported by the head for operating a suction-creating e- :vice, the intake of said suction creating de Vice having communication with the inte rier of the head, and a conduit forming communication with the pressure side of the said suction device and the said casing.

2. A renovator embodying a cleaning head, a casing disposed within the cleaning head and having discharge outlets disposed to direct a blast of air against the surface to be Cleaned, a suction creating device Within the cleaning head a motor supported by the head for operating a suction-creating device, the intake of said suction creating device having communication with the interior of the head, and a separator through which the air currents pass before entering the said casing.

3. A renovator embodying a cleaning head, a casing disposed within and extending across the cleaning head and having discharge outlets disposed to direct a blast of air against the surface to be cleaned, means forremovably securing the casing within the head, a suction creating device within the cleaning head and having its intake in communication with the interior of the head, a conduit exterior of the head and formin communication between the pressure side 0 the suction creating device and the said chamber, said chamber and conduit being detachably connected, and a motor supported by the head for actuating the suction creating device.

4. A renovator embodying a cleaning head, a casing disposed within and extending across the cleaning head and having discharge outlets disposed to direct a blast of air against the surface to be cleaned, means for removably securing the casing within the head, asuction creating device within the cleaning head and having its intake in communication with the interior of the head, a motor supported by the head for actuating the suction creating device, a conduit forming communication between the pressure side of the suction creating device and the said casing, and a separator through which the air currents passbefore entering said casing.

In testimony whereof I have signed my name to this specification, on this 17th day of January, A. D. 1918.
